Electroencephalography (EEG)

Electroencephalography (EEG) is the recording of electrical signals from the brain via placement of an array of electrodes on the scalp.  EEG can be recorded with millisecond-precise time resolution that is not possible with fMRI.  In the PNRC, we combine EEG with fMRI to take advantage of the excellent temporal and spatial resolution of EEG and MRI, respectively.  MRI-compatible EEG recording is used to determine the timing of EEG events and then these can be localized in the brain using the corresponding fMRI response.
